Moving from an Intel-based MacBook Pro (model 15,1) to an M1 Mac is a straightforward process using Apple's built-in tools. Because you are moving from Intel to Apple Silicon, macOS handles the architecture transition in the background.

Before starting the migration, ensure both machines are prepared:

• Update Software: Ensure the source MacBook (15,1) is fully updated within Sequoia.
• Backup: Always maintain a current Time Machine backup before a major migration.
• Power: Plug both MacBooks into a reliable power source.
• Connection: For maximum speed, connect them via a Thunderbolt cable. Otherwise, ensure both are on the same Wi-Fi network.

1. Follow the setup assistant until you reach the Transfer Information to this Mac screen.
2. Select From a Mac, Time Machine backup, or Startup disk and click Continue.

1. Open Migration Assistant (found in Applications > Utilities).
2. Click Continue.
3. Select To another Mac and click Continue.

1. On the M1 Mac, select the icon for the Intel Mac. A security code will appear.
2. Verify the code matches on both screens.
3. Select the data categories you wish to move:
   • Applications: Most will run via Rosetta 2, but native versions are preferred.
   • User Accounts: Includes your files, Desktop, and Downloads.
   • Other Files & Folders: Standard documents and settings.
   • System & Network: Wi-Fi passwords and system preferences.
4. Click Continue to begin the transfer.

• Touch ID: You must re-enroll your fingerprints on the new hardware.
• Apple Wallet: Credit cards must be re-added manually for security.
• Software Optimization: Look for “Universal” versions of your apps to take full advantage of the M1 chip's speed.
• De-authorization: If disposing of the old Mac, sign out of iCloud and use Erase All Content and Settings in System Settings.

Note: If an app was built only for Intel, the M1 Mac will automatically ask you to install Rosetta 2 the first time you open that app.
